A nurse in a provider's office is talking with a client who takes oxybutynin. The client asks why he does not urinate as often. Which of the following information should the nurse include about the action of oxybutynin?
The medication reduces the rate at which the kidneys filter waste.
The medication decreases the sensitivity of the urethral sphincter.
The medication prevents the bladder muscles from involuntarily contracting.
The medication blocks the nervous system impulse to produce urine.
The Correct Answer is C
A. The medication reduces the rate at which the kidneys filter waste: This is incorrect as oxybutynin does not affect kidney function or the rate at which kidneys filter waste.
B. The medication decreases the sensitivity of the urethral sphincter: This is incorrect because oxybutynin primarily affects bladder muscle contraction, not the sensitivity of the urethral sphincter.
C. The medication prevents the bladder muscles from involuntarily contracting: This is correct as oxybutynin is an anticholinergic medication that reduces involuntary bladder contractions, leading to less frequent urination.
D. The medication blocks the nervous system impulse to produce urine: This is incorrect because oxybutynin works by blocking the action of acetylcholine in the bladder, not by blocking impulses to produce urine.

Correct Answer is D
Explanation
A. Pork sausage with sautéed peppers: Pork sausage is typically high in sodium and saturated fats, which can contribute to increased blood pressure.
B. Beef bouillon with crackers: Beef bouillon is high in sodium, which can elevate blood pressure, making it an unsuitable choice for someone with hypertension.
C. A ham sandwich on rye bread: Ham is high in sodium, and consuming it can negatively impact blood pressure control.
D. Broiled cod with broccoli: This is correct as both broiled cod and broccoli are low in sodium and beneficial for blood pressure control. This choice aligns with dietary recommendations for managing hypertension.
Correct Answer is D
Explanation
A. Elevate legs on pillows when in bed: This is incorrect because elevating the legs can reduce blood flow in peripheral arterial disease, and it is generally advised to keep the legs at the level of the heart or lower to promote better circulation.
B. Apply heating pad for 15 min twice per day: This is incorrect because applying heat directly to the legs is not recommended as it can lead to burns or other complications, especially in patients with peripheral vascular issues.
C. Wear knee-high support hose during the day: This is incorrect because support hose can sometimes exacerbate symptoms of peripheral arterial disease by restricting blood flow. Compression stockings are generally not recommended.
D. Begin an exercise program that includes walking: This is correct because walking and other forms of exercise improve circulation and help alleviate symptoms of peripheral arterial disease by promoting better blood flow and cardiovascular health.
